Cornelia appears as ruins in World B, at the Cornelia Plains. In the Confessions of the Creator Scenario, a Teleport Stone can be found near it. Moglin operates his shop here in all storylines where Cornelia is visited. On certain days he will sell one each of rare items such as booster accessories, Elixir-type trade accessories and the Banish/Death and KP Bonus Skills, items sold at no other moogle shop.

The port directly south of Cornelia in Final Fantasy corresponds to the Forsaken Kingdom gateway, which acts as an access point to Order's Sanctuary just off the coast. In Confessions of the Creator, the player's party spawns here at the start of the story, an allusion to the start of Final Fantasy.

Cornelia is also present as a room for customized characters of the game's Multiplayer Mode Online Lobby.

The arcade version of Dissidia remakes the scene of the Warrior of Light gazing at the castle from a grassy hill, an allusion to the opening of the original Final Fantasy and the ending of the original Dissidia Final Fantasy

The original NES localization of Final Fantasy translated this town's name as "Coneria". This is likely a result of the process of converting the word "Cornelia" (a given western female name) to Japanese, the result is "ko-neria", which loses some of the word's nuance. This was re-translated into English as "Coneria" in the NES (which is itself a more direct analog of the Japanese translation of Cornelia) without regard for the name's origin. Later translations took this into account, and properly localized the name as "Cornelia".

Looking into the town well gives a message stating that despite the fact it looks like there may be something of interest at the bottom, it is, in fact, an ordinary well.
